It's possible that your father was a relative of my great grandmother Eduviges Moreno Leal. She was the daughter of Antonio Leal and Zeferina Moreno. Zeferina was the daughter of Jose delos "Santos" Moreno who married Concepcion Garcia Saenz in 1840. He was a rancher in Tamaulipas who earned the LaTrinidad grant fighting for Mexican independence against Spain and named his hacienda Palo Alto. I know Santos and Concepcion had many children and that Eduviges had many siblings. It's said that her siblings had names starting with E. Moreno is a somewhat rare name among the ranching families in south Texas. The neighboring grant to La Trinidad was owned by Juan Moreno, likely a relative of "Santos." Eduviges married Juan Rios of Cadereyta and they had my grandfather Daniel Montoya Rios.
